The first ten years of my mainframe career I never saw a true IBM installation. First I worked with a Fujistu and MSP, then I moved to a shop that had Amdahl kit, and after that a shop that was Hitachi. At least for the Amdahl and Hitachi the OS was really MVS, OS/390 etc.
The Fujitsu environment worked almost exactly the same as the MVS system from the perspective of an applications programmer. The sysprogs probably knew more about the differences than I did at the time. We ran Adabas/Natural, lots of PL/1, SAS, and probably many more besides that I didn't know about (this was my first shop, I was quite young and completely inexperienced of course). Interesting things I remember about the Fujitsu OS: MVS was called MSP - Multiple Systems Product if I recall correctly. But apparently you could see the IBM copyright in the load modules in some places... TSO was called TSS - Time Sharing System RACF was still called RACF - and worked exactly the same Though JCL was the same, we had something called JOL - Job Oriented Language. This was a set of ISPF panels that walked you through creation of each jobstep and built (awful) dynamically allocated JCL. ISPF was called SPF - Systems Productivity Facility We had something called GEM - I forget the acronym, this was a source/version control system if I recall correctly. Used to have to use the TSO SUBMIT and OUTPUT commands a lot - but I guess this was no different from MVSes of the same era (early 80's). We didn't have SDSF.
